Advantages of Water Jet Cutting

Waterjet cutting offers many advantages over conventional cutting methods:

  • Cold cutting - no heat affected zones, no hardening
  • Omni-directional cutting - ability to cut in any direction
  • Perforates most materials without starting holes
  • Cuts virtually any material
  • Net-shape or near-net-shape parts (no secondary processing required in many applications)
  • Minimal fixturing required
  • Environmentally friendly
  • Reduces dust and hazardous gases
  • Does not workload material - stress-free cutting
  • Flexible machine integration
  • Saves raw materials (small cutting kerf width, nesting capabilities)
  • Faster than many conventional cutting tools

Advantages of Water Jet Cutting

One of the biggest advantages is waterjet's inherent cold cutting quality.  This allows materials to be cut that would be burned, melted, or cracked by other cutting methods.  Some thermal processes cause surface hardening, warping and emission of hazardous gasses. In contrast, materials cut with waterjet undergo no thermal stress, eliminating such undesirable results.

Another major advantage is waterjet's ability to cut fiber-reinforced materials, reflective materials, uneven surfaces and stacked layers of different materials.  Since the mechanical processes take place on a microscopic level, the contents and surface finish of the material are not critical factors.

Despite the high kinetic energy in waterjet cutting, part deformation is avoided and high cutting accuracy is achieved without leaving any frayed edges or burrs.  This produces excellent edge quality, which in many cases eliminates the need for secondary finishing processes.

Waterjet cutting is especially advantageous in cutting complex shapes. Materials can be cut into almost any shape.  Sharp corners, bevels, pierce holes, and shapes with minimal inner radii are all possible.  Stacking, nesting and tabbing optimizes material and can significantly reduce cutting times.

Waterjet cutting is particularly "friendly" in regard to the environment.  Normally, the process is clean and does not create grindings, chips, or hazardous gases. Cutting oils or emulsions are not needed.

In today's world of high-priced raw material and limited resources, waterjet's small kerf, or cut width, and part-on-part nesting capabilities optimizes material use, increasing cost-effectiveness.

Using pure water, it is possible to cut textiles, elastomers, non-wovens, thin plastics, food products and many other products.  These materials can be cut at speeds of several hundred feet per minute.

With the addition of an abrasive, harder materials such as metals, stone, bullet proof glass, ceramics, etc. can easily be cut.  Thicker materials can also be cut more efficiently using an abrasive waterjet system.
